摘要: 利用建立的Loop代数A~2的一个子代数, 设计了一个新的等谱问题; 然后利用屠格式获得一族新的Liouville可积的双Hamilton结构. 作为约化情形, 得到了广义非线性Schrodinger方程.

关键词: Loop代数, 等谱问题, Hamilton结构

Abstract: A new isospectral problem is designed by using a subalgebra of loop algebra A~2 established. Then a family of new Liou ville integrable system is obtained by means of Tu scheme, which possesses a bi-Hamiltonian structure.As reduction case, a generalized nonlinear Schrodinger equation is presented.

Key words: Loop algebra, isospectral problem, Hamiltonian structure
